Application filed April- 22, 1927. Serial- No. 1853847.

The present invention rel-ates to templates and the primary object of the invention re sides in the provisionof a template for use in laying out patterns upon cylindrical objects such as pipes orcylindrical rods of various descriptions for the performingof desired cuts. I

A further object of theinven-tion is to: provide a cylindricabtemplate for use in mark ing pipes or othercy'l-i-ndrical objects in a manner whereby the objects may be cut in various manners for accurate end toend fit.

ting at various angles-or-cut in a manner for;

conforming to the external surface of cylin drical objects of a like diameter. a A further object of the invention is top-rovide a multiple cylindrical template adapted to be disposed about a cylindrical object such as a pipe, and embodying features whereby one section of pipe may have an opening layout marked thereon-- and asecond pipe sect on have a marking formed: thereon whereby its: end formation when out will con form to the opening-layout and external surface of the pipe sectionin which, th open t; iS'tO e formed. v v

A still further object of theinvention is r to provide a cylindrical template comprising hinge sectionsfor ready positioning'abont apipe section, and embodying means whereby the pipe section may be. marked and cut for reducing the diameter of the pipe various diegrees;

Other objects and advantages of the in vention will be apparent during the course of the following detailed description, taken in connection withthe accompanyingdraws ings forming a part of this specification and I in which drawings: w

Referring to the drawings in detail, and:- Wherein similar reference'characters designate corresponding parts throughoutthe several views, the improved multiple template hasbeen shown'as embodying a pair of. companion semi-circular shaped-' sections- K 6 and L shown in position fonperfo-rming-thc desired layout upon "a pipesection or similar cylindrical object I Referrin first to the section K; the same embodies a lingered; 50f semi-circular shape in cross section and an edge rod 6, the rodsifi and (i being-joined at theirends by semi-cincular shaped end rods 7 and 8, and which rods '7 and '8 may be either secured asby welding or the liketo the'rods- 5 and: 6, or if so desired the rods 5 to "8. inclusive may be formed froma single continuous piece of material. Extending from the hinge rod 5 to. the edge rod 6 adjacent one end of the tern-1v plate, arev arcuate shaped cross rods 9 and 10: which aside from serving as spacers for the rods 5. and 6,v act in a capacity to besubse-i quently set forth. Carried by the template section K, and arranged from end to. end in Referring now to thetemplate section L,Z the same embodies a hinge'rod 12 ofsemi-cim cular shape in crosssection and an edge rod 13, the rods 12 and 13v being joined at their ends bymeans of "semi-circular shaped end rods 14 and15. The. sectionsK and L. are of a like length and are hingedftogether bymeans of suitable hinges 1 6 connected across the outer side ofqthel semi-circular shaped hinge rods 5 and 12. The edge ro.d;1'3, prefer-4 ably at its center carriesan offset handle l 'l.

which is employed for retaining the sections;

in position about a cylindrical object in a 0 manner as illustrated in Figure l. As will be observed in Figure l, the operator positions his fingers through the handle 1? and by placing the thumb upon the edge rod 6, the template sections are held in position about the cylindrical object to be marked. Connecting the rods l2 and 18 and in diametric relation to the rods 9 and 10, are cross rods 9 and 10 which align respectively with the rods 9 and 10 of the template section K. Carried by the template section L, is a series of gauge members A, B, C, D, E, F, H, I, and J which align and cooperate with the gauge members of thetemplate section K.

The gauge members of the respective sections conform to the shape of the end rods of the sections and unsecured to their respective hinge and edge rods in a manner so that their inner surfaces will contact with the cylindrical object about which the template is disposed. I

While the gauge members of the. template may be; developments of lines formed upon the exterior surface of a cylindrical object for laying out patterns of various descriptions for the performing of desired cuts, in the, example shown the gauge, members have been so shaped as to permit of f cuts being performed for formation of various joints suchv as disclosed in Figure 8. The gauge members of the templates arepreferably of wire like formation of a suitable gauge, but if so desired the gauge members may be of any preferred cross sectional configuration.

-Referring first to the gauge wires A and A, and which also serve as braces for the template sections, these gauge wires may be employed for the making of a cut such as illustrated at a in Figure 3. The companion gauge wires B and B will permit of a lay out being marked on a cylindrical body for providing an angular joint between two sections as illustrated at b in Figure 3. The cooperating gauge wires C and G and which extend at an angle of 45 to the axis of the template, will permit of the right angular joints being formed between two pipe sections as illustrated at a in Figure 3. The cooperating gauge wires D and D will permit of a marking being made upon a cylindrr" cal surface which when the cylinder is cut along said marking may have its end face shaped to fit in surface contact the surface of a cylindrical object as illustrated at cl in Figure 3. As will be observed, the companion gauge wiresD and D have reversed curves at their connection with their respective end and edge rods, and are olfset in a general direction at their connections with.

the edge rods, toward the end rod 15. The cooperating gauge wires E and E, and which extend in a general direction like that of the gauge wires D and D, will permit of a out being formed whereby the end formation of the cylindrical body may be disposed in surface contact with a cylindrical body as illus trated at e in Fi ure 3 for dis oosin the the cylindrical body for making a right an gular joint as illustrated at f in Figure 3 it will be noted in Figures 1 and 2 that the terminals oft-he gauge wires F and F have reverse bends at their terminals and are I joined to their respective hinge and edge rods at diametrically opposite points along the template. Thus it will be seen that the gauge wires D, D andG, G" serve to mark the cylinder in a manner whereby the'cylinder may be cut in various manners for accurate end to wires D, D QE, E andF, F provide markface of a cylinder of like diameter as illustrated at d, e and 7" in Figure V The gauge member G which is carried by the template section K is'of circular formation as at and is connected at diametrically opposite points to the rods 5 and 6 by short s acin wires 21. This circular au e member G serves for markingthe pipe section 2a in Figure 3 whereby a passageway maybe formed between thepipe section 2a and right angularly connected pipe section 25 As'will be observed in Figure 7 the ring like-portion 20 of the gauge member G conforms to thevv curve of the template section K.-

The gauge member H and which is carriedend fitting at various angles, while the gauge,

ice

by the template section L comprises a body portion 26 of ovoid-shape, connected adjacent its wider end bymeans of spacing wires or ribs 27 connected with the rods. 12 and 13 in alignment transversely of the template. This ovoid shaped body portion 26- will pcrmitof a marking being made upon a pipe such as at 28 in. Figure 3 whereby an opening may be cut in the pipe section 28 for forming a pas sageway into the pipe section 6. 1 r

The gauge members I are in the form of gauge wires extending longitudinally of the template and connected at their opposite ends vto thecross rods 9 and '10 and. 9land 10.

These longitudinally extending gauge wires I and I serve for marking any desired longitudinal cuts or perforations to be made in the cylindrical objects and if desired may be sofor marking the, cylindrical-body for a square cut. 7 7 1 The gauge wires or members J and J and which are connected longitudinally of the template between the end rods 7 and l-i-and I'OCS 9 and 9, alternately extend in angular relation to oneanotherin a manner whereby a pipe section may be marked as illustrated at30 in, Figure 3. and after which cut as at 31 andthendrawn together as, at 32 for reducing the diameter of the; pipe to the. desired externaldiameter.

Thus it willbe seenthatthe gauge members of the template asidefrom. permitting in accordance with the specific type of work with which the template is to be used.

From the foregoing-description it will be apparent that a novel and efficient multiple cylindrical template has been provided em bodying hinged sections which may be readily disposed about cylindrical bodies to be marked for cutting, and embodying gauge members whereby the cylindrical bodies may be cut either for-end to end connection or end to side connection with the end formation of one section conforming to the external cylindrical surface of the section with which it abuts.
